Get ready to crank up the chaos factor in this intriguing left-field production brought to you by ELK Studios.

Some game developers commit to churning out new titles at breakneck speed. As such, quality can suffer, and games often feel like content-fillers that do little to fire the imagination or offer anything fresh. The same can’t be said of innovative software suite ELK Studios, who have bided their time and pooled all their creative juices with November 2020 release Nitropolis - a sure-fire contender for the title of ‘Game of 2020’.

Step inside the Nitro Reels™-powered 6x4 reel setup to experience next-gen gaming and prepare to be acquainted with some truly zany nitro-thirsty animals.


The game is set amid some sort of industrial post-apocalyptic world overrun by four clans of a feline/canine nature: the Dirty Dawgs, the Gritty Kitties, the Pug Thugs, and the Rouge Rats. Just who are these oddball characters and how did they wind up here?! We may never know, but it sure makes for some compelling, curiosity-driven slot action.

ELK Studios clearly have some hugely talented folks among their ranks, reflected in the outstanding audio-visual production presented in Nitropolis. The backing track is well-thought out, working effectively in tandem with the gameplay to intensify the action on each spin and amplified further by some clever sound effects.

As for the paytable, it consists of one representative from each of the four clans, plus token playing card icons running from J-A. Payouts for landing up to 6 matching symbols in the base game are on the low side, yielding a max 1x your wager - but this is counterbalanced considerably whenever Nitro Reels™ enter the fray, or by triggering the game’s lucrative bonus round.

Gameplay & Features

In typical fashion, wins are achieved by lining up at least 3 matching symbols across any of the variable betting lines in play, from the left outer reel.

You will find the usual Wild symbols on show here - serving their usual function to replace all other symbols bar the Scatter to help form winning arrangements.

One of the game’s highlights is ELK Studio’s patented Nitro Reels™ mechanism - explained below.

Nitro Reels™

When Nitro Reels are activated, they function by holding anywhere from 4 to 12 identical symbols in place across two symbol places - enhancing your win potential considerably. The game’s Upgrade feature will also occasionally come into play, bumping up the locked number of symbols yet further. And you can help yourself to a second chance whenever the feature decides to randomly respin following a non-winning spin!

In full force, Nitro Reels mean Nitropolis tops out at a quite staggering 85,155,840 ways to win. For comparison, games incorporating Big Time Gaming’s own shape-shifting reel mechanism, MegaWays™, offer players a maximum 117,649 win ways - demonstrating the game’s truly astronomical potential.

Free Spins

Land anywhere from 3-6 Scatters to activate the slot’s Free Spins bonus feature, which furnishes you with 10, 15, 20 or 25 spins, respectively.

Prior to the round commencing, one symbol is selected at random to represent the Scatter. The bigger wins are unlocked whenever three or more of these show up across separate reels, while Nitro Reels also remain sticky for the entirety of the round to help you out.

Nitropolis on Mobile

Nitropolis is playable on pretty much every modern gaming platform imaginable, from iOS and Android to tablet and Windows. The game’s vivid use of colours and immersive gameplay lends itself perfectly to gaming on the go, making this a truly mobile-ready video slot.


Mirroring its high-powered gameplay, Nitropolis is something of a volatile beast - more suited to players who are able to withstand prolonged periods of dry spells, punctuated by the odd generous payout.

The Verdict

We tip our hats to the guys at ELK Studios for pushing the envelope and experimenting with a truly original concept, combined with some blood-pumping gameplay to propel Nitropolis to unchartered heights.

The game’s eclectic mix of concepts, design, symbols, theme and audio combine quite brilliantly to produce something out of the ordinary. What may seem a complex game on the surface soon becomes clear after a few engrossing spins of the reels, leaving you to appreciate the clear time and effort that has gone in behind the scenes.

In addition, a tantalising top prize of €1,000,000 only serves to add further motivation for anyone considering taking a trip to the dystopian wasteland of Nitropolis. All in all this is an outstanding video slot from ELK Studios, earning itself five stars from us.
